LGCJEKIING DEV E FOR LOOSE-LEAF FILES.

1/ '0 c/Z whom it may concern:

Be it known that 1, CHARLES MoBnn, a citizen of the Jnited States, residing at Athens, in the county of Athens and State of Ohio, have invented a certain new and useful linproveinent in Locking Devices for Loose-Leaf 3i es, of which the following is specific-at The object of in y invention is to provide a locldmineans "tor file sheets of? a loose-leaii hinder which will be simple, strong alnd durable in construction, and adapted for use in connection with the posts or a binder on which the papers are threaded, in such a manner as to add strength to the posts, rather than to weaken thein is ordinarily the case.

l ly invention consists oi the details of construction l'ierea'tter pointed out in the the device is locked, and

l 'q 3 shows a similar view, the lever heing elevated to the position it assumes when not locked. in this view the entire spring, and part of the lever, is shown in section.

the like, passing through elliptical slots 21, in the said lever, as shown. The Olll es 1S and 19, are elliptical and are also broader at their outer ends-than at thei" inner ends.

Secured centrally in the plate 16, and underlying the lock spring 17, is pivotally secured a lever 22, provided with a shoulder 23, and having a projecting end 2%, by which it is designed to be rotated upwardly from its mounting, during which operation the shoulder engages and elevates the central portion of the lock spring li. Obviously, the elevation 01' the central portion of the lock spring 17, pulls inwardly each oi the ends of the lever, which, as before stated, are secured to the plate 16 by rivets 20, passing through oblong orifices. The construe tion of the parts is such that as each end of the lock spring 17 is pulled inwardly by the elevating of the lever, 22, the orifices 18 and 19, in the said spring will be in line with their respective orifices in the plate 16, and the posts 14 and on which the lock spring 17 is threaded will lie freely within their rcs 'iective orifices in the lock spring 17, without contact with. the sides of the said orifices.

hen the lever 22 moved downwardly the lock spring 17 tends to flatten out and moves outwardly at each end, by means of the oblong slots aerrnitting the lever to slide to a limited distance each end, on its securing rivets and the construction is such that the inner walls of the orifices in the lool; spring 1'4 engage and bind their respective posts thus locking the plate 16, at the determined point on the posts. A lug 25, is provided on the lower surface of the lock spring l7, to determine the upper limit oi? n'mvcinent on the lever 29..

Having thus described my invention what l claim as new and desire to secure by Letters Patent of the l uited f tates. is:

In a looselea'f file l aving a cover and a plurality of upwardly extending rods the combination. with a plate having openings vhich fit said posts, of a lock spring having elliptical openings adjacent each. end, rivets in said plate, the shanks of which pass through said openings, there being elongated openings in said spring which register with the said posts, said openings tapering ii'm'mwlly and being l'llllOWGl at their inner posts to engage suicl posts and look the plate ends than the diameter of the posts, (b lever against vertical movement. 10
